Swimmer and Swarm Cells (IMAGE)
Caption
Development of swarm colonies and dissemination of adventurer cells in the environment. 0) Planktonic cell attaching to a solid surface; Under swarm inducing conditions, cells can initiate the development of a swarm colony which consists of four stages; 1) Stage I of swarm colony development: colony growth; 2) Stage II of development: differentiation initiation and swarm-flare formation; 3) Stage III of development: swarm-front expansion; 4) Stage IV of development: swarm colony maturation and final architecture formation. 5) Once a mature swarm colony is flooded, a morphologically short and specific cell type is released into the liquid - the adventurer cells. Adventurer cells are highly swimming proficient and can swim towards chitin (a component of seafood) and attach to it.
